The 20 contestants of season 19 were already assigned tribes at the start of the game, but, based only on appearances, the tribes were told to vote one of their own as a "leader", who, for the first half of the game, would make critical decisions at certain challenges - like selecting one member of their tribe to spend the day after reward challenges with the other tribe through which they would receive a clue to the hidden immunity idol.
Amidst triple-digit heat, crocodile infested waters, relentless mosquitoes and terrifying sounds of howler monkeys, the 18 castaways kicked off the 11th season with a grueling 11-mile hike through the jungle.
The ninth installment took place on the islands of Vanuatu, in the waters of the South Pacific near the tumultuous "Ring Of Fire," a land of volcanoes and rituals where sorcery and black magic are a part of tribal life.
Season eight saw the return of 18 players from previous seasons. Given nothing but their water canteens and armed with no information, no fire and no help, the players would be challenged once again to outwit, outlast and outplay one another in order to see who will become the Sole Survivor.
With only the clothing on their backs and a sack of Panamanian currency, the 16 castaways jumped overboard from a boat and swam towards a small fishing village, where their task would be to use the currency they were given to acquire what they'd need to survive for the next 39 days.
After a long journey down the Rio Negro deep into the Amazon jungle in Northern Brazil, host Jeff Probst, in a shocking twist, separated the castaways into a tribe of women and a tribe of men. For the first time on "Survivor," it was the ultimate battle of the sexes.
Separated by gender, two groups of castaways were brought to a small island off the coast of southern Thailand in the Andaman Sea, thinking they were to remain as separate tribes of men and women. After being told that in Thailand elders are "revered," the two oldest players were tasked with choosing tribes, tribal locations and names.
Season four poses an incredible new challenge that sets it apart from previous seasons. Abandoned on a tiny remote island in the South Pacific, 16 castaways are stranded with absolutely no rations of food or water. Separated into two tribes, Maraamu (Wind) and Rotu (Rain), they compete against each other and must live off the land, essentially creating a new society. They must battle the elements and, ultimately, each other.
Season three contestants competed for $1 million in Kenya's Shaba National Reserve. The two initial tribes were Boran and Samburu. In the fifth episode, after 12 days, three members from each team were switched to the other team, in what became known as the first twist in the Survivor series. This season was also the first to have a tiebreaker challenge.
Sixteen players roughed it in Goshen Station in northern Queensland. It was the top-rated show of 2001. The second season was the first and only season to last 42 days instead of 39, meaning that the rapid-fire elimination of a Final Four turned into a Final Three. This series also began the Survivor tradition of revealing the results live, so that none of the castaways would know who won until the finale.
It all began in Borneo with 16 people marooned on an island, working together to survive, but ultimately trying to outwit, outlast and outplay each another. Every three days, the Survivors must gather to vote someone out of the tribe. The lone Survivor at the end wins $1 million.
